The ________ ion is represented by the electron configuration [ar]3d2.
Tresset [83]
The Ti 2+ ions is  represented  by  electron  configuration  (Ar)3d2. Titanium is in  atomic  number  22  and  its  electronic  configuration  is  (Ar)3d2 4s2.  Titanium loss two  electron that  is  4s2 electrons  hence the  electronic  configuration ( Ar)3d2.  4s2 is  the  valence electron  hence  it   the  one   which  is  lost  to  form  Ti2+

Please solve for Cu,N,and O an dif you can show how cause ik confused
belka [17]

Cu⇒ 1 atom

N⇒2 atoms

O⇒6 atoms

Total 9 atoms

<h3>Further explanation  </h3>

The empirical formula is the smallest comparison of atoms of compound forming elements.  

A molecular formula is a formula that shows the number of atomic elements that make up a compound.  

<em>(empirical formula) n = molecular formula  </em>

Chemical formula : Cu(NO₃)₂

Number of Cu : 1

Number of N : 2

Number of O = 2 x 3 = 6

Total atoms in Cu(NO₃)₂ : 1 + 2 + 6 = 9

Which of the following statements about subatomic particles best characterizes electrons? A positive charge, light, circling the
schepotkina [342]
Every electron carries one elementary negative charge.  Concerning mass,
it takes roughly 1,840 electrons to make enough mass for 1 proton or 1 neutron.
Electrons don't necessarily have to stay connected to an atom, but when they do,
they circle the nucleus.

So you should select (C): ==> Negative, ==> light, ==> circling the nucleus.
